Comment 8 for bug 92354

Description of problem:
I setup an Xorg config under a Xen guest to use the evdev driver for input
instead of /dev/input/mice, since the former honours absolute pointer events &
thus avoids the insane 'double mouse' issues.

There appears to be a bug in the evdev driver though. If moving the cursor in
the X-axis only, or in the Y-axis only it works fine. If I move the cursor in
the X & Y axis at the same time (eg bottom-left -> top-right of screen), the
position of the cursor on screen seems to 'loose' the X co-ordinate updates
until I finish moving the mouse.

eg, move from bottom-left -> top-right of screen, while the mouse it moving the
cursor will only update the Y co-ordinate. When I stop moving the mouse, it
finally updates the X co-ordinate

Version-Release number of selected component (if applicable):
xorg-x11-drv-evdev-1.1.2-3.fc7

How reproducible:
Always

Steps to Reproduce:
1. Boot a Fedora 7 paravirt Xen guest
2. Configure it to use attached Xorg config file
3. Start X
4. Move mouse at a medium speed from bottom-left to top-right corner of screen

Actual results:
Mouse moves up left-hand side of screen, and then at last movement flips over to
top-right corner

Expected results:
Mouse moves smoothly diagonally across the screen from bottom-left to top-right.
